Suburban Furnace No Heat

[Joyce and Richard Hayden]



Curt,

I had to get a new NT16 for the FC a few years ago because the heat exchanger was leaking. It had the front cover issue as stated by Chuck and I used the old one. On the PT I have always been able to fix/clean the heater to getthen workingto work. I also remove themto clean and bench test. When I did the units on the PT I don't think they had ever been removed and cleaned. Cleaning works wonders. I did have one, the center one, that had a bad thermostat. Discovered that after I had done all of other things I could think of.

Ralph,

I'm just getting started with this project and building my alternatives sheet.

Usually there is no heat, minimal heat once in a while with t-stat at max. T-stat, fan, click, all seem OK. I can see fire thru the glass when it produces minimal heat

Yesterday I removed the unit. Removed the ignition/sensor unit and cleaned it although is looked fine. The adjustments are correct. Burner looks great. Little dust using compressed air in the fire box.

Need to continue checking...

What sort of issue? Do you hear a click click click and no fire? do you hear one solid click first then click click click? Does the fan run?

Have you removed the front panel, then the cover with the sight glass and cleaned the probes with a tooth brush? Ran a long cone brush that is used in the house on the drier lint vent, to clean the top of the beaver tail?

Is the circuit board getting the signal from the thermostat? Just some thoughts before replacing, these units are usually pretty bullet proof but the circuit boards will go out from time to time.

Safe travels,

Having the no heat issue from the center propane heater, Suburban NT16 SW.

Suburban tells me the NT16 SW was designed for Wanderlodge…the W for Wanderlodge. The NT16 SE looks to be the same unit. Suburban could not tell me the difference in the two units. Anyone have that knowledge?

Anyone know if the NT16 SE can be used as a direct replacement for the NT16 SW without modifications?
